Application tiled August 19, 19119. Serial No. 46,099.

To all whom t may concer/n:

Be it known that I, ADnLMER M. Barns, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Valve-Bags, of which the following is a specication.

My invention relates to valve bags provided With handles. Its object is to securely attach to the bag a handle which will not interfere with the filling of the bag but will serve for the easy manipulation of the bag after it has been filled. It is illustrated as applied to a paper Satchel bottom bag in accompanying drawings Wherein- Figure 1 is a side elevation of the bag co1- lapsed, with handle and filling tube parts shown in dotted lines. Fig. 2 is an edge View of the bag of Fig. 1, the filling tube removed. Fig. 3 is a cross section on the line 3 3 of Fig. 1.

Like parts are indicated by the same letter in all the figures. l

A. A. are the sides of the bag.

lB is the valve opening.

C is the bottom of the bag which is normally folded flat against the side of the bag, and when the bag is hung up for filling, will appear in the position indicated in Fig. 2.

D is the top of the bag secured at one end to the fabric of the bag, but at the other disconnected therefrom so as to make the valve opening B. rIhis opening is protected or valved by the interior flap of material indicated at E in Fig. 1.

F is an inside handle member preferably consisting of a fla-t surfaced strip placed longitudinally and parallel with the aXis of the valve opening and a little at one side of the middle line of the top of the bag, and

againstA the inner surface of the top of the bag.

G is the exterior handle portion, which in this case is shown as made of heavy twine, applied so as to form a closed loop. rIhe two ends of the exterior handle portion are` carried ou*I in opposite directions parallel with the interior member and each end is secured to the interior member preferably by two staples G2, G2, which are inserted from the outside, overlying the ends of the exterior` member, passing through the bag material, through the interior member and are then clenched into the bottom of the in-` staples which pass through the fabric of A the bag.

rIhe interior handle member in assembling is introduced through the valve of the bag and is preferably at one side or otherwise ositioned or shaped so as to make the intro notion of the filling tube J easy.

'Ihe structure consists of a finished valve bag with a handle comprising an interior member applied to the inside of the bag after the valve and bag have been completed, an exterior handle portion whose ends outwardly extend and are parallel with the, interior member and staples which secure the parts together. 'Ihis is a statement of the exact detailed structure of the device as experience has shown it is best to make it.

It is understood that my invention is primarily intended to be applied to paper bags or bags of soft and not particularly durable material. It is necessary thatl the rigid or sti" inside handle memberbe so positioned that the full load or lweight of the bag as it hangs on the filling tube be not applied through the paper to the rigid handle member, because owing to the, fact that paper is relatively inelastic, this would result in such a concentration of the load at one point as might tear the bag. I put my handle mem ber therefore at the side of the valve, so that while this handle member rests on the tube, still the major portion of the load applied by the bag to the tube along the line where the tube intersects a vertical axial plane, is not applied through the handle, but directly from the bag to the tube along the total length of the tube.

I claim:

1. A handled bag consisting of a bag closed at both ends, but provided with la valve opening at one corner of' one end, and a handle comprising a longitudinally extended inner portion in line with but at oneside of the axis of the valve opening, a ilexible exterior portion, and staples whereby the two portions are secured together through the fabric of the bag, the exterior portion bowed in the middle with ends projecting outwardly in each direction substantially parallel with the interior portion.

2. A handled bag consisting of a bag closed at both ends but provided with a valve opening at one corner of one end, and a handle comprising a longitudinally extended inner portion in line with but atene side of the axis of the valve opening, a lexible exterior portion in the form of a loop whose ends lie parallel with the inner por tion, and staples which pass through the fabric of the bag and secure the inner and outer handle portions together, the exterior portion bowed in the middle with ends projecting outwardly in each direction substantially parallel with the interior portion.

3. A handled bag consisting of a bag closed at both ends, but provided with a valve opening at one corner of one end, and

of its axis and below the line of contact between the tube and bag, an exterior handle portion and means whereby the two portions are secured together through the fabric of the bag.

In testimony whereof, I ailix my signature, in the presence of two witnesses, this 13th day of August, 1915.
